    - Referencing Assembly Problem Hi, I have a curious problem using VS.NET 2002 I create a new class library with a public function Public Class ASN1 Public Sub New() End Sub Public Sub test() MsgBox("test") End Sub End Class Now I open a new Solution, Add a new Reference to the DLL (in bin directory). now I can use DIM and I even see the test method in the object browser BUT .. Dim asn1 As New components.ASN1() <- here it shows me the class names! asn1.... <- it does not show my any methods here What could be the reason for this?!! On a different PC with VS.NET 2003 this works without problems. Is this a VS.NET 2002 bug? kind regards Oliver Drobnik Tag: Checking to see if a event handler has already been registered Tag: 67340

    - PrintDialog fubar ? Hopefully, I'm missing something here, but this is my problem : I instantiate a PrintDialog object and set the PrinterSettings property. I call ShowDialog, and the user selects PrinterResolution and Landscape values. Now, because these properties are in PageSettings, not PrinterSettings, there is no way to find out what the user selected ?

    - WebResponse Headers comma delimiting mistake The expires date in a Set-Cookie header includes a comma in every implementation I have seen or read documentation for. However, the CLR's WebResponse Headers collection delimits headers of the same name with commas. I thought I would get around this with the Headers collection method GetValues("Set- Cookie"), but even at that point the headers have already been corrupted by storage as a comma delimited string. Is there a way around this with the CLR? Basically, the WebResponse Header methods Get and GetValues are bugged because they use a comma delimited string to store the headers. I assume somewhere the real headers are available, but probably not available in public. I assume this problem was allowed to occur in the name of code reusability by way of the NameValueCollection. Where can I report this bug? Does anyone know of a workaround or a way to access the headers in their raw line delimited form? Is the CLR source available for perusing? -AB Tag: Checking to see if a event handler has already been registered Tag: 67319

    - What's everyone's beef with Crystal Reports? At one of the VSLive! Orlando sessions there was much disdain expressed for Crystal Reports for .NET by many. I'm wondering what the major issues are, as I've always found it a pretty and effective tool, albeit not the most intuitive thing to figure out. (And I've always wished you could save and reuse formulas, but I understand that's now a feature in v. 10) I like some of the things they've done with the Enterprise version, but I'm skeptical about the licensing costs if I get serious about that direction. Is that the major problem? Tag: Checking to see if a event handler has already been registered Tag: 67289

    - Run VS assembly using VSA Hi, I would like to compile a dll in Visual Studio and have it run using the VSA runtime wrapper class. I've tried to load an assembly using VSA runtime engine but I get an exception stating that the _Startup class cannot be found. I've examined a working VSA assembly which contains (amongst others) a class called _Startup. Also the project file (.vsaproj) for the assembly isn't a compatible Visual Studio project file. Can this be done or is it better to pursue a solution based upon loading late bound assemblies at runtime and executing them?

    - Detect encoding of a text file Folks, I have a number of text files in a directory, and I'd like to know what type of encoding they're in. I thought I could just open a StreamReader for each file one at a time, and let .NET determine the encoding (Default, UTF-8, Unicode) - there's a nice constructor for StreamReader which takes a file name, and a boolean "detectEncodingFromByteOrderMarks" which I figured would do exactly what I want - open the file and see if it's a Default (ISO-8859-1), UTF-8 or Unicode (UTF-16) file. Here's my function: public string DetermineFileType(string aFileName) { string sEncoding = string.Empty; StreamReader oSR = new StreamReader(aFileName, true); sEncoding = oSR.CurrentEncoding.EncodingName; return sEncoding; } But that doesn't seem to work - in this case, *all* files are being labelled as "UTF-8", which I *KNOW* is *NOT* true.... Is there any easy way in C# to let it determine the file's encoding reliably? Do I really need to "manually" look at the first three bytes of each file? Any ideas??

    - VC and WAB integration. I have one more query but this time it is related with Windows Address Book(WAB). Suppose I open a link to WAB through my application's (developed in VC++) dialog box. Now, if I get the focus back on my dialog box with the WAB still opened(not in focus though), I cannot navigate through the controls in my dialog box through the TAB key. Also, ENTER key does not work. But the dialog box starts responding to the TAB and ENTER keys as soon as WAB is closed. Why is it happening like this. I had downloaded a sample WAB program from www.microsoft.com and this program too had the same problem. I want to know if it is a bug or a normal behavior in VC++ and WAB integration. Is there any workaround to this problem. I had put up this query long back to mssupport@grapecity.com but did not get any response. Hope I wont be disappointed this time.

    - Excel/Outlook interop Hi, All! I'm working on a C# windows service project in witch I'm using MS Excel and MS Outlook automation objects referenced through Microsoft Excel 10.0 Object Library and Microsoft Outlook 10.0 Object Library. On my local computer, calling methods and accessing properties on these automation objects works smoothly. However, when I try running the service, having deployed it on the production server, the execution halts on the first attempt to invoke a method or access a property on one of the automation objects. Strange thing is that no exception is thrown, the service just halts and doesn't seem to get any further in execution. Consider the following code snippet: //-> Excel.Application xlApp; Excel._Workbook xlWbk; Excel.Worksheet xlWst; xlApp = new Excel.Application(); // <-- The call to the Excel.Application constructor returns OK. // However, neither of the following lines of code are ever executed. // The execution of the service just halts, waiting for control to be // returned from the automation object. --> xlApp.AlertBeforeOverwriting = false; xlWbk = xlApp.Workbooks.Add(Excel.XlWBATemplate.xlWBATWorksheet); //<- Just for the record, I've copied the versions of Interop.Excel.dll, Interop.Outlook.dll, Interop.VBIDE.dll from the the project directory on my local computer, onto the production server, in the same directory as my Windows Service executable.

    - command line compile to a different framework version Hi, I have the professional version of VS.NET 2003. I know only the enterprise version will allow compiling to a diff version of the framework, but I thought maybe there was a command-line feature in the professional version that might allow me to do the same thing. Does anyone know? Thanks, -c Tag: Checking to see if a event handler has already been registered Tag: 67196

    - Converting UTF8 -> ASCII I'm trying to convert a UTF8 string to an ASCII string, but the code I've tried isn't working. <code> private static string Utf8ToAscii(string value) { byte[] utf8Bytes = Encoding.UTF8.GetBytes(value); byte[] asciiBytes = Encoding.Convert(Encoding.UTF8, Encoding.ASCII, utf8Bytes); return Encoding.ASCII.GetString(asciiBytes); } </code> Am I doing something wrong?

    - silent assertion of assembly existance on client machine Hey I need to assert from within a web page that an assembly was previously installed (and registered) on its hosting machine. I want to attempt to create an instance of that assembly inside a java or vb script method and decide according to the results whether it had been installed. The following line of code works in javascript but generates a warning massage I want to avoid (regarding activeX involvement in the page...) : var myObj = new ActiveXObject("myRegAsem.regAsemTest"); Is there a silent method I can use instead??

    - Need info on how to debug customer systems. My development team develops .NET custom software for resell. If we receive a report of an application in the field that has a bug, we would like to be able to remotely connect to the live system (with proper user authorization) to be able to debug the application remotely (preferably with process attach). Currently the only way we can determine how to do this is to use the remove debug components in VS.NET. Is this the only way to do remote debugging? We are not sure if these components are redistributable. I have also looked into the CLR debugger, but once again we are not sure if the .NET SDK is redistributable. -- ----------------------------------- Ken Varn Senior Software Engineer Diebold Inc.

Before registering a new event handler with an event, is there a way to
check to see if the event hander has already been registered?

Also, is there a way to de-register all eventhandlers that have registered
with an event?
